The alphabet list gives the program characters it can use to scramble the message. The key will later be used to store the information to unscramble the message. And the path will ask the user for what they want to do.

The Program

First we need to ask the user for what they want to do. Let's start with the encryption part.

Now we have the part of the program that unscrambles the message. This part of the program does that by taking the odd number characters from the key and replacing them in the scrambled message with the even characters.
